Specification of Letters Patent.

Patented Nov. 24, .1914.

Application filed February 20, 1914. Serial No. 819,871.

To all whom it may concern Be it known that I, EDWARD P. PULLEN, a citizen of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Sifting- Top Cans, of which the following is a specification.

My invention has relation o a sifting top can for use as a container for powdered caustic soda commercially known as lye, as well as being adapted for use for containing other substances or composition materials; and in such connection my present invention relates particularly to the specific structural detail arrangement of the members constituting the sifting top of the can of the character as defined for the particular use mentioned, among other uses therefor.

The defined members of the sifting top can, embrace a can-body having a sunken head expanded to securely engage the wall of said body and with an expanded central circular projection struck up in the .head and having a down turned wall surrounding an opening to the can-body, the said projection forming a seat for a perforated plug adapted to be inserted in said opening terior wall of the said central projection of the sunken can-head as well as affording an opportunity for readily prying off with a sharp edge tool, when necessary, the same thereby providing a sifting top can as a whole, in which the contents of such container may be readily removed either slowly by sifting the contents therefrom upon free ing the cover from the perforated plug which it conceals or' rapidly by removing both cover and perforated plug, so that the contents of the can may be discharged in bulk through the opening of the said central projectionin the sunken can-head.

The principal objects of my present invention are first, to provide a can of the character defined that'can be rapidly and conveniently seamed upon the can-body;

second, a cover for such a can which is air tight when the can is notin use and which can upon removalofthe coverWill permit of either satisfactorily sifting the contents therefrom or permit of the removal of the contents in bulk from the can ad Zz'bz'tum; and third, toprovide a can for substances or composition materials in which in case'of the calling of such contents, the plug can be readily'removed so as to permit of such oaked contents being freely or quickly dischargedthrough the opening in the central projection of said sunken can-head.

My invention stated in general terms, con sists of a sifting top can, consistingof three members constructively arranged in substantially the manner hereinafter described and claimed. a I

The nature, characteristic features and scope of my present invention will be more fully. understood from the following description taken in connection with the accompanying drawings forming part hereof, in which I I I Figure 1, is a view in diagram structurally of the three members of the can-top in position as shown, to be assembled to constitute one form of a sifting top can, em-

bodying the essential main features of-my said invention. Fig.2, is a similar diagram, showing respectively the-members of the,

can-top, in which one member, the sunken vcan-head is fitted with a perforated plug and inwhich theothermember the head bracingthe sameand constituting the three members of the said top. Fig. 3, is a similar View of a slightly modified structural arrangement'of the said three members separated from each other as shown,,and in which one of the members, the perforated plug has resting on the face thereof a disk of parafiin paper or the like for sealing the apertures of the plug and preventingthereby when the cover is applied to allthree members assembled of the caking of the composition material over the surface of the said plug and inner surface of'the cover of the said can. Fig. 4, is a top plan view .of the can with its sealing cover removed,

to show how the top flange of the perforated plug rests on the face of the central projection. of the sunken c an-head thereof.

Fig. 5, is a vertical central sectional view through the can on the line it, w, of Fig. i, showing the arrangement of the sifting top of the can with the sealing cover applied thereto, illustrating structurally the type of can with its top of Figs. 1 and 2; and Fig. 6, is a similar view of the type of can-top as structurally illustrated in Fig. 3, with an interposed parafi ined or like character disk applied between the cover and perforated removable plug and resting on the said plug of the sunken can-head secured or seamed to the can-body as part thereof.

Referring to the drawings, particularly with reference to Figs. 1, 2, 4: and 5, a, is the circular metal cover provided with a bottom outwardly curled bead a to stiffen the same and thereby to aid in the provision of an air tight closure for a can when applied thereto and moreover to afford with facility when so applied by the application of a sharp edge tool under the curled bead of the prying off of the same.

b, is the metal head or ring of the top intended to be seamed to the can-body A. lhis head or ring is provided with an embracing right angular peripheral rim 6 to be seamed to the said body and inward of the said rim the said head orring is formed into a sunken part at and which terminates in a vertical circular projection 6 having a down turned wall 5*, to. provide a central opening to the interior of the can-body A.

0, is a perforated metal plug fitting the wall 6*, of the opening of the said projection Z2 and is formed with a peripheral flange or rim 0 to rest on the surface 12", of said projection F2 and with a depending wall 0 to snugly fit the said wall 6*. The walls and 0 respectively may be either vertical as shown in Fig. 1, or inclined or made sloping as shown in Fig. 2, to lightly engage each other or tightly as may be preferred. By providing the plug with the peripheral flange or rim to rest on the surface If, of the projection 6 the plug 0, is thereby prevented from being pushed too far accidentally or otherwise through the opening of the said projection in the assembling of the parts of the can-top or at any other time when the cam is provided with its composition or other powdered material.

The members of the top as above defined are stamped out in approximately the shape or condition shown in Fig. 1. In the process of assembling they are first placed in the position as shown in Fig. 2, and then portions of the respective walls 5 and 0 are expanded outwardly to secure the perforated plug 0, thereby in firm bearing connection with the sunken head or ring 6, yet not so securely as that the plug cannot-be removed by prying it'off and outof the opening of the centralprojection -Ea, of the sunken head or ring I), of the can-top. After the head or ring 6, and plug 0, have been assembled in preferably the manner above explained, the cover a, is then applied to the exterior wall of the projection 6 of the said sunken canhead or ring as shown in Figs. 2 and 5. lhe top is then ready to be seamed by the peripheral flange or rim 6 to the can-body A, in any well understood manner.

When the can is to be used, after having been filled with the material for which it is intended, the cover a, is removed and the contents of the can may be sifted through the series of perforations 0 thereof or if preferred the plug 0, may be pried off by inserting an instrument with a narrow edge between the face of the projection 6 and flange orrim c of the plug, to thus enable the contents of the can in bulk to be freely and quickly discharged through the central opening of the projection 6 of the sunken can-head or ring 6.

In Figs. 3 and 6, are shown a slightly different structural arrangement of the top to that hereinbefore described, but however, embodying the same idea of a combination cover with arrangements for either sifting or pouring the contents from the can-body A, through the large central opening in the projection 6 of the can-head or ring I).

In Fig. 3, particularly the plug is shown with a struck up angular peripheral flange c, and with a series of sunken perforations 0 in the body of the said plug. This plug so arranged fits against the wall I), of the projection Z2 of the can-head or ring I), and having its peripheral flange resting on the top surface of the said projection for supporting the same in position.

The foregoing arrangement is not as desirable as the close fitting cover to the plug to provide an air tight can in view of the space left when the parts are assembled between the plug and the removable cover a, in which in shipping in such a type of filled can the contents freeing itself through perforations cakes above the plug unless a waxed, paraflined or similar paste board paper or thick disk (Z, is inserted over the perforations of the said plug to rest thereon as shown in Fig. 6. It may be here remarked that with such a space to contain the said applied disk (Z, the latter serves when so used to contain directions for the use of the contents of the can as well as the name and location of the maker of the composition material of such can.

Having thus described the nature and objectsof my invention, what I claim as new and desire to secure by Letters Patent is:-

The combination with a can-body, of a head provided with a peripheral rim b seamed to said body and inward of said rim formed with a "sunken portion Z2 and therefrom formed into a vertical circular projection 6 having a down-turned Wall 6, surrounding a central opening, said vertical projection extending above said rim, a perforated plug fitting the wall 6, formed with a peripheral rim 0 to engage the surface 6 of said vertical projection and having a downwardly depending Wall 0 fitting snugly said Wall 6 to prevent the plug being pushed too far accidentally or otherwise into the opening of said can-head and a cover a, provided With a down'turned flange terminating in an external bead a, said flange fitting snugly over thevcircular projection 6 thereby providing an air-tight closure for said can-head.

In Witness whereof, I have hereunto set my signature in the presence of the tWo subs scribing Witnesses.
